IMPROVEMENT IN ROOFING COMPOSITIONS.

Specification forming part of Letters Patent No. 172,321, dated January 18, 1876; application filed June 26, 1875.

1'0 all whom it may concern:

Be it known that I, GARLETON B. HUToH- ms, of Ann Arbor, county of Washtenaw and State of Michigan, have invented a new and Improved Composition for Goverin g Roofs and various other uses, of which the following is a specification:

The nature of my invention consists in mixing melted rosin, indurated pine-tar, paraffine oil or rosin oil, eitherseparate or combined,

with wheat-bran, coarse mid'dlings, fine mid dlings, cattles hair or tow, ground mineral paints produced from Brandon, Vermont, or ground stone and pulverized alum, in a manner hereafter set forth, either to be increased or diminished, as may be wished.

To prepare the roofing I take equal parts of melted rosin and tar, or either of the oils, to the amount of ten gallons each add to this one pound of cattles hair or tow, sixteen quarts Wheat-bran, sixteen quarts coarse middlings, twenty quarts fine middlings, and

ground stone or mineral paint enough to make the compound of suitable thickness to spread Well.

ing of paint covered with bran makes the surface of a lightish color when embedded in the paint, which serves to throw 0d the rays of the sun and preserve the compounds, and not overload the roof, as when covered with gravel.

I claim as my invention- The composition fabric roofing and roofingpaint, of the ingredients and in the proportions substantially as set forth.
